very few reviewed studies linked restoration to sustainability
Restoration and sustainability connections are rarely studied
A systematic review of 46 peer-reviewed studies on psychological restoration in natural settings examined how often each study linked restoration to different outcomes. Mental health outcomes dominated, appearing in 52% of studies. Education came up in 20%. Sustainability, meaning connections to green infrastructure or ecological aims, appeared in only 7% of the reviewed studies, and peace building in just 2%.
For those shaping green space, curricula or environmental programming, this points to a gap: the evidence base linking restorative natural settings to sustainability goals is thin compared with the mental-health literature. Anyone wanting to justify green infrastructure or ecological education on restoration grounds is working with far less research support than the mental-health framing might suggest.
This is a count of how many studies within one review addressed each theme; it tells us how much research attention each topic received, and it cannot show whether restoration actually improves sustainability outcomes, since the 7% figure reflects coverage in the literature rather than any measured effect size. The review draws only on Scopus and Web of Science, covers 46 studies, and points to a gap in existing research design; it says nothing about restoration itself being ineffective for sustainability.

While 52% of the studies reported links between psychological restoration and mental health outcomes, fewer addressed connections to education (20%), sustainability (7%) or peace building (2%).

Architect
A nature view needs 35 per cent greenery to lift satisfaction
When the value engineering round opens and the glazing spec is first in line to be cut, you defend a nature view only by naming the effect figure that justifies it.
Asset manager
No certification premium attaches to the nature view on its own
A certification premium prices the whole label into rent and exit value, but it never tells you which single measure inside the building earned it.
Corporate real estate manager
Outward views reach staff cost through sleep and stress
Optimised daylight and views came with 37 minutes more sleep and 42 per cent higher cognitive scores, and a 2006 REHVA guidebook puts staff cost at 100 to 200 times a building's energy cost.
Developer and investor
No study ties a rent premium to the nature view
Nature views change measurable outcomes in people; the link from there to rent stays a category average, not a per-building figure.
HR manager
A view of nature restores attention
Berman and colleagues validated attention restoration on a backwards digit-span task, and cognitive control is rated strong; on retention there is one study, and it dates from 1998.
Marketing manager
A nature-view claim is safe only as a description of the view
For the real estate marketing lead: a nature-view study measured 37 extra minutes of sleep under one tested condition, and this worksheet sets the boundary an exposé sentence must keep to pass an advertising review.
Workplace strategist
Nature views lower reported stress and sharpen attention
Boubekri and colleagues measured 37 more minutes of sleep and a 42 per cent gain on cognitive scores: a capex paper defends that figure only by naming the author and the limit a finance committee will probe first.
